Geochemical Characteristics of Rare Earth Elements in the Chaluo Hot Springs in Western Sichuan Province, China

High-temperature hydrothermal activity areas in western Sichuan Province, China are ideal objects for studying deep Earth science, extreme ecological environments, and comprehensive geothermal utilization. To understand the geochemical characteristics of rare elements (REEs) Chaluo hot springs authors analyzed composition fractionation REEs through hydrochemical analysis, REE tests, North American Shale Composite-normalized patterns. Moreover, complex species water area were determined calculation simulation analysis using Visual MINTEQ 3.0 software. The results as follows. In terms type, all is Na-HCO 3 type. cations mainly controlled by water-rock interactions evaporation, anions interactions, processes primarily dissolution silicate minerals. total content 0.306 ± 0.103 ug/L. It low compared to Kangding affected reductive Fe oxides/hydroxides, followed pH. rich light (LREEs) because presence oxides. shows positive Eu Ce anomalies due combined effects Eh Mn oxides surface water. Furthermore, also caused between Qugasi Formation Similar alkaline bodies, include Ln(CO ) 2 − , LnCO + LnOH 2+ which stability constants complexation reactions.
